What are 2 differences between 2D and 3D images?

2D is "flat", using the horizontal and vertical (X and Y) dimensions, the image has only two dimensions and if turned to the side becomes a line. 3D adds the depth (Z) dimension. This third dimension allows for rotation and visualization from multiple perspectives.

What is difference between 2D and 3D image?

Straight lines make up the sides of the 2D shapes. 2D shapes are drawn using X-axes, and Y-axes. 3D Shapes: 3D stands for “Three Dimensional”. A 3D shapes have three dimensions- Length, Breadth, and Height or Depth.

What are 3D medical images?

3D medical imaging is a revolutionary optical imaging technology, which provides enlarged image of the interior body for medical analysis by utilizing 3D imaging modalities. The 3D imaging technology includes ultrasound, magnetic resonance imaging (MRI), radiography, and computed tomography scan (CT).

Why the use of 3D images are important in nuclear medicine?

By gathering sufficient volume data, analysis and quantification of 3D images give valuable information in medical diagnosis. Angular measurements on body structures are often crucial for analysis of the data for diagnosis.
